    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 f<$>?o&y  
    WPN4mEow  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: )yOdRRP  
    enableservice('AutomationServer', true) e?V7<7$  
    enableservice('AutomationServer') T@S\:P  
    b!h*I>`  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 'UW(0 PXw  
    EINjI:/D  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 08+cNT  
    1. 在FRED脚本编辑界面找到参考. lVw77bZ  
    2. 找到Matlab Automation Server Type Library CXe2G5  
    3. 将名字改为MLAPP tJ_6dH8Y  
    MHm=X8eg  
    f4h|Nn%;  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 vZ rE9C }

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fW'@+<b  
    1. 创建Matlab服务器。 T[z}^"  
    2. 移动探测面对于前一聚焦面的位置。 S m%\,/3  
    3. 在探测面追迹光线 {D6E@a  
    4. 在探测面计算照度 JFJ_ PphvD  
    5. 使用PutWorkspaceData发送照度数据到Matlab BeNH"Y:E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 aT]G&bR?  
    7. 用Matlab画出照度数据 y,i ~w |4  
    8. 在Matlab计算照度平均值 _0v+g1x  
    9. 返回数据到FRED中 x=/`W^t2
